To all whom it may concern:

Be it known that I, DANIEL SULLIVAN, of Central Falls, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Fronts for Steam Boilers or Generators; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanyingdrawings, forming apart of this specification, in which- Figure 1 shows a front elevation, Fig. 2 a section, of my boiler-front.

Same letters show like parts.

My front can beinade of comparatively thin iron, while retaining equal or greater strength than the ordinary cast-iron front now in use, nor is it liable to crack or break from unequal expansion or contraction.
